FUEL MIXER FOR INTERNAL-COMBUSTION ENGINES.

Application filed August 21, 1926.

The main object of this invention is to provide a gaseous fuel mixer adapted to be interposed between the intake pipe of a manout in the claims.

yA structure embodying` the features of my n invention is clearly illustrated in the accompanying drawing forming a part of this application, in which:

Y Fig. lis a side View of a carburetor and manifold with my improved fuel mixer in operative relation thereto, the carburetor and manifold being` indicated conventionally by dotted lines.

Fig. 2 is a front l`view ofiny improved mixing device.

Fig. 3 fragmentary vertical central section through the discharge of a carburetor and the intake of a manifold with my device in operative relation. thereto.

viiig. 4lis a fragment of the filling material preferably employed by me.

Fig. 5 is a front View of a slightly modified form` of my improved mixer.

Referring to the drawing, l represents a carburetor and@ the intake manifold of'an internal combustion engine. The carburetor is provided with an attaching flange 4 while the manifold has a coaeting attaching fia-nge 5.

lily improved mixer comprises a plate-like holder G adapted to be interposed between the flanges el and 5, the plate having openingsv 7 registering with the carburetor and inanifold passages. I provide a receptacle 8 formed of wire screen and a cover 9 also formed of screen. The edges of the receptaeie and cover are engaged in the annular groove l0 in the plate 6, the edges being sprung inte this groove or retained therein.

by the resilience of the materialforming these parts.

lVithin this ieceptacle is a filler material designated generally by the numeral 1l formed of a fabric l2 knitted from non-con rodible strands preferably of copper, the fabric being loosely crumpled upon itself and arranged in the holder so as not to offer any considerable obstruction to the passage of air, but does serve to collect and mix with the air any 'unvaporized fuel. i

vrfhe receptacle is preferably rearwardly tapered as illustrated and when disposed in a horizontal position as shown in Fig. l, the upper wall 13 of the receptacle has a greater inclination than the other walls as shown lin lfig. 8 so that there is less of a body of the filling material at the top of the passage. rihis affords a minimum of ob- -stinctionto the passage of the carbureted air and the heavier unvaporized fuel being carried along in the lower part of the pas-V sage is caught by the filling material and mixed or vapor-ized. Where the device is to yoccupy a horizontal position I do not distort the receptacle, it being regular in form as indicated at 14C in'Fig. 5.

My improved mixing device is highly efficient, does not become clogged and offers comparatively little obstruction to the passage of the air.

Having thus described my invention what l claim as newand desire to secure by Letters Patent is:

l. A device of the class describedcomprising a plate-like support adapted to be inten posed between the intake pipe of a manifold and a carburetor and having` an opening therein registering therewith, the edge lof the opening having an annular groove therein, a receptacle and a cover therefor formed of wire screen disposed with their edges in said groove, said receptacle being disposed to project into the manifold and being rearwardly tapered, and a filling of knitted metal strands crumpled loosely and arranged in said receptacle, the upper wall of said re- Y ceptacle having an inclination substantially greater than the other walls thereof so that there is less obstruction at the top than at th` ein ofthe deviceJb 2 Y 1,711,7ee

2. A device of the class described comprising o plate-like support adapted to be interposed between the intake pipe of a manifold and :L carburetor and having an opening 5 therein registering therewith, the edge of the opening having an annular groove therein, a receptacle and e cover therefor formed of wire screen disposed with their edges in Said groove, and a filling of knitted metal Strands crumpled loosely and arranged in said reoeptacle.

In witness whereof I have hereunto set my hand.
